Bruce Schneier has an excellent article in Wired that encompasses two of the memes I have written about previously: The importance of perspective during terror events (both individual and societal), as well as how we need to make sure that we don't create a self-fulfilling prophecy by indicting all people of faiths that are not ours (which would be 'everyone else' for me, being an atheist).
"But our job is to remain steadfast in the face of terror, to refuse to be terrorized. Our job is to not panic every time two Muslims stand together checking their watches. There are approximately 1 billion Muslims in the world, a large percentage of them not Arab, and about 320 million Arabs in the Middle East, the overwhelming majority of them not terrorists. Our job is to think critically and rationally, and to ignore the cacophony of other interests trying to use terrorism to advance political careers or increase a television show's viewership."
